A crumbling British industrial city (filmed at London's docklands) is the bleak setting for gangs of aimless youth who steal cars, crash into the windows of various shops, grab whatever comes to hand, and then lead the police on high-speed chases. Adrenaline junkie Billy (Law) is accompanied by thrill-seeking girlfriend Jo (Frost) on one such escapade while fending off rival Tommy (Pertwee), who doesn't like his burgeoning criminal empire disturbed. Tries too hard for that rebel youth feeling.
